. SHOE-POLISHING- MACHINE.

To all-whom it may concern:

Beit known that I, SALVATORE GIANDALIA, SON or ANTONIO, a subject of the King of Italy,residing at Auburn, in the county-of Sangamon and State of Illinois, have invented new and useful Improvements in Shoe-Polishing Machines, of which the following is a specification.

This invention relates to improvements in coin controlled shoe polishing machines.

An object of the invention is the provision of a machine of this character, in which the depositing of the coin will release a predetermined amount of cleaning liquid, which. will be conveyed to the shoes, whereupon a set of brushes will operate over the shoes to clean them and prepare them properly to receive a polish.

Another object of the invention is the provision of a shoe polishing machine having mechanism released by the depositing of an additional coin, to distribute over the surface of the shoes a suitable polishing liquid and to start the operation of polishing brushes, whereupon the surface of the shoes are brought to a bright polish.

Other objects and advantages of the invention will appear as the following de-.

' scription is read in connection with the accompanying drawings.

electric wiring for operating the mechanismi Referring. to the drawings in detail,

wherein like characters of reference denote the shoes, being hereinafter referred to as the polishing mechanism. The cabinet 11 is provided with a pair of openings 12 throughwhich the shoes are adapted to be inserted to be acted upon by the cleaning mechanism and positioned adjacent these openings is a chair or seat'13, for the convenience of the person whose shoes are'being cleaned. The cabinet isfurther provided with a pair of openings 14 for the passage of the shoes to be polished, While a chair or seat 15 is also positioned adjacent these openings.

Referring in detail to the cleaning mechanism. the same includes an electric motor 16, which is adapted to drive a crank shaft 17 through the medium of worm gearing 18. The shaft 17 is mounted in suitable bearings 19 and is provided with a central crank 20 and connected to this crank is one end of a pitman '21. Pivotally connected to the opposite end of the pitman 21 is a block 22 and depending from the bottom of this block is a I cross head 23, the latter operating in a longitudinal guide 24. Extending rom opposite sides of the block 22 are brushes 25,

these brushes being adapted to act upon the and which operates in a longitudinal guide; 31fdisposed parallel to the guide 24. The block 29 carries bristles 32, which extends inwardly toward the foot rest or block .26

' and as this block is duplicated u on the opposite side of the brushes-25, t ey are 7 adapted to act upon the outer side of the shoe.

The heels of the shoes are cleaned by means of brushes 33, which are carried by blocks 34 and these blocks are alsoprovided with cross heads 35, which operate in a guide 36 disposed at right angles'to the guides 24 and 31. The blocks 34 are connected as shown at 37 and are operated through the medium of a pitman 38, one end of which is pivotally connected to one of the blocks 34 and'the 0 posite end connected to a crank arm 39, W ich is located at one end of shaft 40. This shaft is mounted. in bearings 41- and is driven by bevel gears 42 from the crank shaft 17 at the other end.

In order to provide for shoes of different widths, the guides 31 are pivotally mounted at one end as shown at 43 and are urged inward toward the foot rest 26 through the medium of springs 44. These sprin s surround short rods 45, which pass t rough ears 46 and are provided with adjusting nuts 47. The rods 45 pass loosely through openings in the ears 46 so as to provide for predetermined quantity of flui proper play when the guides 31 are moved upon their pivots and for this purpose, the connection between the pitman 28 and the crank 27 is also loose. By reference to Figure 4 of the drawings, it will be seen that the arrangement of cranks 20 and 27 are such as to cause the brushes 25 and 32 to move in opposite direction foraction upon the inner and outer surfaces of the shoes.

For the purpose of supplying a suitable cleaning liquidto the shoes, there is provided a tank 48, which is located in a compartment 49, the latter being formed by a partition 50 which extends entirely across the top of themachine so as to separate the liquid supplying mechanism from the brushes and their operating -mechanism. The machine is designed to sup ly only a operation and to' accomplish this there is provided a pair of pipes 51, each of which extends downward over a foot rest 26 and terminate in branch pipes 52 of substantially U-shape in plan. These pipes are located directly below the openings '12 and are provided with inwardly-extending preferably rubber nipples .53, which are adapted to contact with the shoes, so that the liquid discharged therefrom will be deposited upon the shoes. The pipes 51 are provided with alternately operated valves, the upper valves 54 being located adjacent the tank 48 and being connected by a rod 55 so as to operate in unison. The lower valves 56 are. spaced from the'valves 54 and a section of the ipe between these valves is so proportione as to hold only a sufficient quantity of fluid for These last at each 'ings register with the openings in the dpipes means of a rotatable member in the form of a disk or cam 58, the latter being mounted upon a shaft 59 which also carries a worm wheel 60. The worm wheel 60 is driven by a worm gear 61 mounted upon one end of a rod 68, which rod is connected to one of.

the valves 54. The opposite end of the arm 67 has connected thereto an arm 69 and this arm is connectedb means of a rod 70 to a pivoted lever 71. ne end of the lever 71 is located in the path of movement of a In 72 which projects outwardly from the periphery of the rotatable member or cam 58, the said lug being u on the sameplane as the said member. The rotation of the member 58 will thus operate the valves 54 to bring the openings in these valves in register with the openings in the pipes 51 to permit of the passage of liquid through the valves. The length of the lever 71 is such as to hold the valves in open position for sufiicient length of time to permit the proper quantity of liquid to pass therethrough. As this occurs, the valves 56 are in closed position so that the liquid will be trapped between the valves in the pipes 51.

The valves 56 have projecting therefrom.

shaft 75 carries at its lower end an arm 76,

which is connected to av pivoted lever 77 through the mediumof a rod 78. The lever 77 is located in the path of movement of a lug 79 which is also carried by the rotatable member 58, but is located in a plane above the upper surface ofthe said member so that the lug 79 will not engage the'lever 71 in its movement By this means after the liquid has passed through the valves 54 and been trapped within the pipes 51', when the lug 79 engages the lever 77, the valves 56 will be operated to permit the liquid to pass throughthe openings in these valves, when, the said open- 51, whereupon the liquid will pass ownward through the pipes and. ni les 53 onto the shoes.

or the purpose of starting the operation of the motor 16, a coin is deposited in a slot. 80 and during its passage through this slot, the weight of the coin will rest upon a switchmember 81, which is pivoted at one end as shown at 82 and forms a portion of the bottom of he s t 80 as illustrated in through the rod 1,420,540 r i a Figure 9 of the drawings. 0 When the switch member is depressed, it engages a'contact member 83, which is connected by means of a conductor 84 to a magnet 85, the said magnet being connected by a conductor 86 to a battery or other source of electric energy 87. The switch member 81 is connected by a conductor 88 to the opposite side of the battery, so that when the circuit is closed by the weight of the coin the magnet 85 will be energized. This operation will attract an armature 89 which is located in the field of the magnet 85 and will close the circuit in which the motor 16 is included so as to start the operation of the motor. This closing of the motor circuit occurs when the armature 89 engages a contact 90, whereupon current will flow through a conductor 91 connected to the contact and from the battery 87 through a conductor 92 which connects the armature with the motor and a conductor 93 which connects the opposite side of the battery with the motor. When the armature 89 has been fully attracted, its end will engage under a spring latch 94, one end of which will be depressed to engage a contact 95, to which is connected a short conductor 96, which is tapped onto the conductor 91 leading fromthe battery 87. Current will thus pass from the battery 87. through the conductor 91, the conductor 96, the pivoted latch 94, through a conductor 97, which is tapped onto the conductor 92, through the motor 16, the conductor 93 and to the opposite'side of the battery 87. The mechanism will thus be operated for a suflicient length of time to properly clean the shoes and when this has been accomplished, the circuit will be broken by means of a lug 98 which extends from the rotatable member 58 in a plane below the lower surface of the same, the arm 99 of the latch 94 being rotated in the path of this lug, whereupon .the latch will be operated to release the armature 89 which is moved in a direction away from the magnet 85 under the influence of a spring 100. The circuit will then be broken and the operation of the motor ceased.

After the shoes have been properly cleaned, they are inserted through the openings 14 to be acted upon by the polishing mechanism. This mechanism includes a liquid supplytank 101, having communicating therewith pipes and valves, similar to the pipes 51 and valves 54 and 56 described in connection with the cleaning mechanism. These pipes convey the liquid to the shoes through branch pipes 102 and nipples 103 which are located directly beneath the openings 14.

The brushes for polishing differ from the brushes of the cleaning mechanism and comprise a pair of arched shaped members 104, which are provided with polishing pads 105, the latter being covered by flannel or-other suitable material 106, which is adapted to contact with the surface of the shoe so as to provide theproper luster. The pads 105 are mounted within thin spring metal arches and have pivotally connected thereto one end of pitmans 106, the opposite ends of which are pivotally connected to cranks 107, provided in a shaft 108. This shaft is mounted in suitable bearings 109 and is driven by worm gearing 110 from a motor 111, similar to the motor 16 previously described. The purpose of forming the arch members of resilientmaterial is to permit them to give or expand for shoes of different sizes and to hold the polishing pads 105 in close contact with the shoes. The polishing pads 105 are further provided with pads 112 and these last mentioned pads have connected to their upper surfaces bowed springs 113 and 114. The spring 113 has secured thereto a headed stud 115, which operates in a slot 116 provided in the metallic portions of the brushes 104 The spring 114 has also connected thereto a headed stud 116 which also operates in said slot, but this last mentioned stud has connected thereto one end of a spring 117, whose opposite end is secured to the brush 104 as indicated at 118. The purpose of this is to permit the polishing pad- 112 to give upon the inward stroke of the brush 104, the said brush making a complete stroke at each operation of the crank 107,

'while the pad 112 will only move a distance determined by the size of the shoe being polished.

The brushes 104 have projecting from each side thereof a pair of rods 119' and loosely mounted .upon the outer ends of these rods are Wheels 120. These wheels revolve in upper and lower opposed U-shaped tracks 121, which are mounted in brackets 122 suitably secured within the machine. Mounted upon the rods 119 and interposed between the brushes 104 andthe wheels 120, are coil springs 123, the latter acting to center the brushes 104 and to permit of lateral movement in each direction, so as to insure proper contact with the shoes. serve to polish the toe and both sides of the shoes and for this purpose of polishing thev heels, there is provided brushes 124, which are provided with polishing pads similar to the pads 105, the said brushes being guided in the tracks 121 and being maintained in, proper position through the medium of the rods 125 and the springs 126. The brushes 124 are operated by means of pitmans 127, which are connected to cranks 128. These cranks are formed in a shaft 129 which is driven by means of a shaft 130 and bevel gearing 131.

The polishing mechanism is operatedin the same manner as the cleaning mechanism previously described, that is by the insertion of a coin in a slot132, which coin operates The brushes 104 I in the manner previously described to energize a magnet and close the motor circult for the operation of the motor and the ro-' tatable member for the operation of the valves for supplyin a coin receptacle or drawer 133, while the coin from the slot 132 is deposited in a similar receptacle or.drawer 134. Suitable normally closed. fillin openings 135 and 136 are provided for-fil ing the tanks 48and 101 respectively. p
